The obvious definition is a room or space for working with audio production. However Audio Suite is also the name Digidesign coined for host based plug-ins in their systems. A TDM Digidesign system has proprietary DSP devoted to plug-in processing, but Digidesign also makes a number of systems where the host computer provides all of the processing (whether it’s in real time or not). Plug-ins designed to work on that type of hardware from Digidesign are known as Audio Suite plug-ins. This is analogous to VST or Direct X plug-ins, just specific to Digidesign hardware.
